Definitions

  • the invention relates to a method and a device for the pollution-free removal of pollutants and waste materials with a low calorific value, in particular waste, by incineration.
  • the term “pollutants” and “waste materials” is intended to include, in particular, domestic, municipal, agricultural and industrial waste without excluding other substances, provided that they contain portions of combustible substances.
  • leachable heavy metal compounds enter the biological cycle and accumulate during waste composting. Case by case there are also harmful organic compounds and / or coli bacteria, Salmonella and other pathogenic bacteria in the compost.
  • landfills Similar dangers of soil and groundwater contamination also exist in landfills. Leaching or decomposition processes as well as enrichments allow pollutants, poisons and pathogens to enter the soil and groundwater from such landfills. In addition, landfill sites are hardly available in densely populated areas, are a nuisance to the populated area, and cannot be used as a building land and land of use for decades after a landfill has closed.
  • Municipal household waste which is often disposed of in complex waste incineration plants in metropolitan areas, contains, for example, fuel components with an average calorific value of 2000 to 2200 kcal / kg.
  • Garbage incineration plants which were promised decades ago a solution to the garbage disposal problem, have been in the flue gas recently and not because of their pollutant emissions
  • Leach-resistant, in particular heavy metal residues in the fly ash or the wash water fall into the firing line of public criticism. Some of these plants therefore had to be shut down.
  • the furnace does not reach the temperatures necessary for the safe decomposition of organically toxic compounds such as dioxins or polychlorinated biphenyls.
  • the heavy metals that get into the fly ash or wash water are also not bound in a leach-resistant form and accumulate to dangerous concentrations when they are deposited.
  • a disadvantage in addition to the cost increase is the difficulty of keeping the combustion temperature on the grate almost constant in the event of fluctuating material content of the waste.
  • Waste incineration plants are therefore also subject to considerable difficulties and risks in the pyrolysis process.
  • the invention has for its object to eliminate pollutants and waste materials by combustion in such a way that no polluting pollutants arise or are emitted, and that the heat content contained in the waste materials is used economically and technically sensible.
  • a device suitable for this purpose should cause significantly lower investment and operating costs than those incurred, for example, in a conventional waste incineration plant.
  • the device should be suitable for economically advantageous and technically problem-free coupling with an existing pyrotechnic system, for example a cement burning system.
  • the object is achieved with the method according to the invention in that the combustion process is carried out in a combustion unit with the supply of hot combustion air as an energy source of such a high temperature that combustion and / or flue gas temperatures of at least 1250 ° C. are reached.
  • the incineration of garbage with the supply of hot combustion air advantageously enables a temperature range of 1250 ° C to be reached even if the calorific value of the flue and waste materials to be incinerated is low and, as with garbage for example, they also burn with a certain moisture content .
  • Compliance with the specified temperature range is advantageous because, on the one hand, there is complete decomposition of almost all pollutants, such as cyclic hydrocarbons or toxic compounds of sulfur, halogens or holgenides, alkalis, etc., and on the other hand compliance with this limit in the range up to 1250 ° C practically prevents the thermal formation of harmful amounts of toxic nitrogen oxides.
  • pollutants such as cyclic hydrocarbons or toxic compounds of sulfur, halogens or holgenides, alkalis, etc.
  • one embodiment of the method provides that the temperature of the combustion air is set in accordance with the calorific value of the substances to be burned or in accordance with the combustion and flue gas temperatures.
  • one embodiment of the invention provides that the combustion air is fed to the combustion unit at a temperature in the range between 600 ° C. and 950 ° C., preferably at approx. 800 ° C. becomes.
  • the desired high-temperature combustion is preferably achieved without the addition of other fuels and the hot combustion air is sufficient as an energy source to initiate and maintain a clean, environmentally friendly combustion process.
  • an embodiment suggests that the combustion process be carried out with a proportion of hot combustion air that is at least balanced in relation to the fuel proportion becomes.
  • combustion air for the combustion process of the pollutants from the clinker cooling process branched off hot cooler exhaust air flow and flue gas from the pollutant combustion process is introduced into the system of the cement clinker combustion plant.
  • the return of the exhaust gases from the firing process into the system of the cement kiln also enables an economically and technically sensible use of their heat content, for example in the calcination of the raw meal, during its preheating, or in a grinding drying system upstream of the cement kiln.
  • the introduction of the gases in the calciner, cyclone heat exchanger and mill drying has the advantage that pollutants contained in the exhaust gas are adsorptively or chemically bound to the goods . As a result, the emission of these pollutants is largely or almost completely prevented.
  • the known method has the disadvantage that the quality of the combustible material can be considerably reduced as a result of the mixture with the waste.
  • the CaO content of the fired product is between 30% and 70%, preferably between 40% and 55%, the amount added advantageously being set in accordance with the type and amount of the pollutants to be separated from the resulting gas.
  • carbonate-containing material in the form of a dust cloud can be introduced into the exhaust gas in accordance with the pollutants to be separated from the gas, and the exhaust gas can be cleaned of pollutants such as S0 2 by the dust filter acting as a reactive retention filter.
  • the flue gases generated in the firing unit are introduced at locations where sufficiently long reaction times and the presence of reactive cement raw materials, such as in the calcination zone, allow sufficiently long reaction times to favor the adsorptive or chemical bonding of pollutants to the cement raw materials.
  • the invention makes use of the known measure of partial gas extraction (bypass).
  • an embodiment of the method provides that mineralized residues of the pollutant combustion process are at least partially added to the firing material of the cement kiln and optionally burned, cooled and / or ground together with the clinker.
  • the fuel product in the case of a pollutant content, can be processed to a consistency just before further use or rejection, in which pollutants are present in a bond that precludes any danger to the environment.
  • This consistency of the firing product can preferably be produced by hydration with or without the addition of additives and / or other binders.
  • combustion residues which mostly contain ash, slag and / or small amounts of metals, can in many cases be easily added to the cement clinker without reducing its quality.
  • the waste disposal device By designing the waste disposal device with a separate, self-contained firing unit, there are not only the advantages mentioned above when coupled with a plant for firing minerals such as cement, but also with advantage also the possibility to optimize the combustion process of the waste materials and independently the combustion process of the minerals.
  • the ignition temperature and especially the willingness to ignite of the waste materials is reliably achieved even with a low calorific value by connecting the combustion unit to a hot gas source, the supply of high-quality fuels, which has so far been frequently required in waste incineration, as an additional energy source is eliminated.
  • the combustion unit can advantageously be designed to be relatively uncomplicated in comparison to conventional waste incineration plants, in particular if it is designed with a fluidized bed combustion unit. This results in significant savings in investment and operating costs.
  • cement raw meal for the addition of lime-containing carbonate carriers is extremely inexpensive and constantly available without major transport problems.
  • the preheating and calcining station 1 comprises a preheating and calcining station 1, a firing station 2 and one Cooling station 3.
  • the preheating and calcining station 1 is charged with a calcareous carbonate carrier 4 in the form of a flour.
  • This material is heated in direct heat exchange in counterflow to hot furnace gas 5 of the firing station 2 and at least partially calcined.
  • fuel 6 is supplied to cover the heat requirement in the endothermic calcination process.
  • the heated and partially deacidified raw meal 7 reaches the firing station 2 in the further course of the process. This is also given to waste 8. Waste 8 and deacidified raw meal 7 are intimately mixed with one another in the firing station 2 and, if necessary, fired with the addition of fuel 9 at temperatures above 1250.degree.
  • the garbage 8 is reacted with calcareous and in particular carbonate-containing substances 4 at temperatures, for example around 1350 ° C. and higher, to give the fuel 10.
  • This passes from the burning station 2 into the cooling station 3, where it is cooled with cooling air 11 and discharged as the end product 12.
  • the cooling air 11 heats up and is introduced as hot combustion air 13 at temperatures between 800 and 1000 ° C. into the combustion station and, if necessary, generates a high-temperature waste incineration there with additional fuel 9.
  • exhaust gas 14 is eliminated from the process.
  • Fig. 2 shows a similar process family tree, also with the basic three stations, namely the preheating and calcining station 1, the Firing station 2 and aer cooling station 3.
  • the preheating and calcining station 1 is preceded by a mill-drying station 15 for the carbonate carrier base material 4 '.
  • This is fed into the mill drying station 15 in a pit-damp state and dried therein in the exhaust gas stream 14 and ground into flour in a purely schematically indicated comminution device 16.
  • the mill drying device for the exhaust gas 14 additionally acts as a reactive or adsorptive filter through which the exhaust gas 14 is additionally cleaned. If pollutant residues are nevertheless present in the exhaust gas 14, this can be fed to a known gas cleaning system.
  • the gas discharge 17, which branches off from the combustion station 2 achieves a considerable discharge of pollutants in the gas household of the method.
  • elements which tend to evaporation or condensation cycles such as halogens or sulfur at a harmful concentration, are at least partially withdrawn from the combustion process by the gas vent 17.
  • the gas withdrawn can be supplemented by hot combustion air 13 from the cooling station 3 by a bypass line 18.
  • waste 8 is fed into a pyrolysis station 19.
  • this waste 8 is subjected to a dry distillation with the supply of heat in a chamber in the absence of oxygen. External heating 20 is used for starting until carbonization gas 21 arises. This is fed to the fuel feed 9 of the burning station 2.
  • a branched-off partial stream 22 of the carbonization gas covers the heat requirement of the pyrolysis station 19.
  • Waste 8 is introduced into the chamber with the exclusion of air and pyrolysis residue 8 'is fed in after the gasification of the waste from the combustion station 2 and mixed therein with deacidified raw material 7 and to the combustion product, as already previously described, fired or sintered.
